Specification of Letters Patent.

VApplication led November 13, 1917. Serial No. 201,778.

` To all lwhom t may concern:

Be it known that I, JOHN E. JOHNSON a citizen of the United States, residin at lgin, county of Kane, and State of llinois, have invented certain new and useful Improvements in Watchcases, of which the following is a specification.

This invention has general references to watch cases, but relates more particularly to a means of pivotally connecting the bow to the case center.

In watches of the bracelet or wrist style, it is common to secure to the case center oppositely disposed bows or loops to which strap sections or the ends of a bracelet may be attached. It is desirable that the bow should be pivotally mounted on the center. so as to be capable' of swinging toward the wrist. With the endinview of devising an improved bow for this purpose, and Yone which will permit of the strapbeing easily and securely connected thereto, the present invention has been devised. Other objects also will appear from the detaileddescrip- 'tion to follow wherein reference is made to a preferred embodiment of the invention as illustrated in the accompanying drawing.

Figure 1 is a face view of a bracelet watch of conventional design, securing strap sections being shown attached thereto;

Fig. 2 is an enlarged edge view thereof; Fig. 3 is a detail of the swinging bow, the parts being disassembled to better exhibit their construction, and

Fig. 4 is an enlarged cross section through the bow in attaching position, its several parts being in assembled relation.

The watch illustrated in Fig. 1 is provided with the usual case center 5 on which is mounted a pendant 6 and two bows 7, each alike, and capable of receiving the looped ends 8 of complementary strap sections 9. Each bow is pivotally connected to a joint 10 which, in the form shown, is provided with feet 11 extended through the walls of the 'case center and turned to lie on its inner side tosecure the joint in place. The joint is formed with the usual cylindrical aperture through which a pin 12 may pass, the pin shown in the drawing being hollow or tubular. The bow comprises two separable ends 13 adapted to .aline with each other when inserted within a sleeve 14, and each connected with a tubular portion 15v adapted to aline with the joint 10. The pin 12, when inserted through the tubuI1 ar portions 15 and-the joint 10, serves as a pintle on which the bow may swing, and its ends 16 may thereafter be spread or upset, as appears best in Fig. 4, to overlie the endsiof the tubular portion 15 for the purpose `of Patented Sept. 3, 1918.

maintaining the parts of the bow in permanent relation. It will be understood that, lduring the process ofV assembling the bow,

the sleeve 14 with the ends 13 inserted thereinto, is arranged within the looped end 8 Of onel of the strap sections 9, so that the strap will be properly and securely at# tached to the watch.

It should be evident that the present bow can 'be very simply made, and readily as-` sembledE on the watch. The maintaining of the parts in permanent relation is accomphshed by the simple expedient of upsetting .the ends of the pivot pin 12. By forming thepin hollow or tubular, the turning of the ends may be readily accomplished by the use of a revolving tool having a conical acting head. While I have shown and klescribed a bow construction designed particularly for watches of the bracelet or wristlet style, it should be understood that my invention may be applied to other cases as well, and may also be embodied in other forms, and I do not, therefore, desire to be restricted to the exact construction herein shown except as my invention may he limited in its scope by the appended claims as follows. j

I claim:

1. A case having a joint secured thereto' a bow comprising end sections in alined relation, 'alined tubular portions connected with the end sections,v and a sleeve adapted to receive the end sections; and a pintle extended through the tubular' portions of the bow and through the joint affording a pivotal ,connection therebetween, substantially as described.

2. A case having a joint secured thereto; a bow arranged for pivotalv connection with the joint, the bow being split to provide separable end sections each formed with a tubular portionl adapted to aline with the joint i i f Y i mimos? atA each end, with a head serving to afford pintle inserted through the joint and 4tuinia' 1pivotal connection between the bow and lar 'portions ofthe bow forming a pivotal joint and to maintain the end sections of connection therebetween, the pintle 'ends be. the bow against separation, substantially as ing fiared to overlie the ends of the tubular *5 described. v portions of the bow, substantially asn de-I 1t' 3.
